Here's an interesting one.. I hope.

I'm looking for a new oil filter for Gerrard, as you do..

I found that the following part numbers are all after market suppliers that are allegedly compatible with the 115bhp diesel donkey. I believe the Fiat part number is 46796687 but ePer is off the road at the moment.

Whilst the diameter "d" (76mm) and the seal diameter "d2" (72mm) are the same, the height "h" of each filter is different:

Mann 7003 - h53mm
UFI 23 455 00 - h61.5mm
Bosch 0451 103 300 - h67mm
Mahle OC458 - h73.5mm

UFI (who I think is the OE supplier) makes a pretty small filter (though not as small as Mann). Bosch looks like "near enough to make no difference) but Mann and Mahle have quite different opinions how big the filter should be..

As a fan of "fit the biggest bastard one that will physically fit" (assumes more filter area and space for the beast to do it's filtery business) I'm tempted by the Mahle doodah ... but why are the filters different sizes and does it make any theoretical difference?

I'm assuming each manufacturer just makes use of existing stampings and parts to create a filter that does the job for a particular engine.. and in reality there's no pro's or con's against a big or a small filter... but I'm curiouse if anyone knows anything...

Strangely, the forum 2004 copy of ePER lists 46796687 as suitable for the Stilo JTD, however my later 2014 version of ePER says that part number is only suitable for the Idea, Multipla, Bravo and Lancia Musa JTDs. The later ePER lists it as part number 71753742. This is the part number I've always used in both of my JTDs.

When considering which filter to use, it's not only the filtering element, but also whether it has the correct tension bypass and anti drain-back valves fitted. That's the main reason I only use the genuine Fiat 71753742 one.

Aha! I can see your 71753742 and I raise you with a 46796687!

Interesting this Fiat one is 65mm high. I'm inclined to think the truth is not that exciting.. just "it doesn't really matter"...

The 717... number looks like the new number for 467... though dunno why the old number is listed as current on the new ePer, if that's the case..

There's nothing in ePER to say it's a changed part number. Both numbers are still available, but listed for different vehicles.

I have tended to always use Mann filters, air and oil... on standard applications where possible, the one I have on now is not a Mann, I had one on before when I did the service but had a new sump fitted when my gearbox was replaced and this one seems much longer...my Mann one was about an inch stubbier.

Aye! The Mann one is 53mm tall. It's the shortest filter listed.

My exisiting filter is a Mahle (from memory) so it looks enormous by comparison. Anyway, this time I got a good deal on the OE Fiat filter, so I'll fit that.

If I might add, I was also a fan of ` the biggest filter that could possibly fit` , and I mounted one on my 16v JTD that was almost the double the size of the original shallow one but still it did fit ok. guess what happened? After driving around for a while and car got to operating temperature, I started to get LOW OIL PRESS warning on the dashboard and I stopped . After letting the engine cool a bit, I started driving again, no issues, bought a proper filter , similar to the one that was on before, fitted it and everything was fine again.

To cut long story short, the new, bigger filter that I installed , was sitting too close to the exhaust manifold (about an inch clearance) and the oil was getting too hot therefore triggering the low pressure warning !! Mind you, I am talking about the engine which has a proper oil cooler. Learned my lesson that time.


Hope this information will help someone


Thanks
